The object of the game is to lead Frogger across the Third Kingdom, which is filled with evil creatures and insects in search of the Princess of his wishes. There are many user interactions in the game that gives hints and tips on how to complete each level. There are a set amount of coins and gems to collect in each level for a bonus score (optional), and special stones that will allow Frogger to use special abilities. Frogger has a few different attacks, which consists of a melee attack, and a ranged attack which he will spit green guck from his mouth. It also features neat jumping physics. Upon pressing the jump button, if you press it again and hold it, Frogger will blow up his cheeks and slowly glide to his destination, this is efficient for getting from a high ledge, lilly pad, cliff, etc. to a lower one. Frogger can also swim in this game.
The game is more of an adventure than a challenge, being particularly aimed at children. Unlike most computer games, the PC port doesn't have options to change the resolution or overall graphic quality, thus making the world appear jagged and rough. The game is well known for its inaccurate controls and lazy camera view. The game is sometimes compared to Rayman 2: The Great Escape and Rascal in terms of graphics and overall themes.
Frogger is the main protagonist of the game. He hears a story of how a frog turned into a prince by being kissed by a princess, and sets out on a quest to find a princess of his own to turn him into a prince. He is aided by the Fairy Frog Mother, and a great source of allies, but also has his share of enemies, such as the Goblins, frog-eating fish, scorpions, snakes, vampire bats, the Rough Bunch, the Bone Cruncher, the Mad Scientist, and the Magical General.

Fairy Frog Mother is Frogger's guide throughout the game. She is a very powerful fairy, and usually appears to Frogger in the most desperate situations, such as when he is trapped in Dr. Starkenstein's Castle. Throughout the game, she provides helpful advice and strength for Frogger, but it ends up being his turn to help her when she is captured by the Magical General.

Phroi the Fairy is a fairy who lives in Fairy Town, and considered the leader of the faries there. Frogger first meets him by helping him recover from his sickness in River Town, in exchange for allowing Frogger to meet the Fairy Princess...after he completes five tasks (Fairy Games). Although Phroi keeps his promise of letting Frogger meet the Fairy Princess, she is not the one Frogger is looking for.
The Magical General of Light and Industry is the main antagonist of the game, despite his minor appearance. He is responsible for the events of the game. He may or may not have been responsible for the disappearance of the King and Queen, but instantly took the chance to use the Goblins' jealously of the kingdom's freedom to wage war on it. He captures Princess Joy and plots to use her to become King. After Frogger defeats him, he leaves but vows to return...
King Ijnek is a primary antagonist in the game, but like the Magical General, is rarely seen despite this. He is hated by those who fear him, but is frequently abused by Big Mama, so Ijnek takes it out on everyone else, including Frogger. He leads the Goblins in their attack on the Third Kingdom.
Dr. Starkenstein, also known as the Mad Scientist, is clearly a mad scientist. He created Geeky Bill and Stinky Phil, as well as the Metal Chicken Ray.

When Frogger arrives at Bog Town he asks them how he could find a princess. Gavin is shy and walks away from Frogger, but Blair is friendly and gives Frogger some advice on finding a princess by telling him to talk to Bruiser the Bear.
Bruiser the Bear is a big, blue bear that lives in a cabin located in Bog Town. In exchange for some honey, he leads Frogger to Slick Willy's "River Princess", which Frogger believes to be a real princess. Not only does he not get along with the bees, he's allergic to them.

Hiss the Cat Dragon is a cat dragon who resides in a canyon above Fairy Town. Phroi and the fairies send Frogger to get a ride from Hiss as part of the fourth task.

He makes an appearance at Joy Castle after the final battle.
Princess Holly, also known as the Fairy Princess, is the princess Frogger meets after completing all five of Phroi's tasks, but is not the one he is looking for. She warns him that the princess he is looking for is in need of his help. She magically transports Frogger to the Dark Trail Ruins.
Wild Thing is a goblin-like creature that meets Frogger in the Dark Trail Ruins. He tells Frogger to watch out for the "Stinky Biggies" (Bone Cruncher) above. When Bone Cruncher chases Frogger, Wild Thing shows the young frog a way out and tells him to shrink Bone Cruncher. Frogger then catches Bone Cruncher and Wild Thing shows him the way to Dr. Starkenstein's Castle.
Bone Cruncher the wolf-like monster is encountered when Frogger travels through the Dark Trail Ruins. He is referred to as "Stinky Biggies" by Wild Thing. Bone Cruncher may have some connection with the establishment of the original civilization, possibly worshipped by it. Frogger uses a Shrink Stone to shrink it down to a small size, but when he uses it later before his final battle, Bone Cruncher returns to normal size (thanks to Fairy Frog Mother) and chases off some of the Magical General's guards.
Geeky Bill and Stinky Phil are two creatures created by Dr. Starkenstein. They ambush Frogger at the end of the Dark Trail Ruins and carry him to Dr. Starkenstein's Castle.

A tall, giant chicken that breaths blue, poisonous breath attacks Frogger while he destroys the laboratory and then chases him out the exit and traps him at the entrance to the Catacombs.
Count Blah is a vampire who resides in the Catacombs, but unlike typical vampires, Blah only drinks fruit juice. He originates from fruit bats, but there were vampires on his mothers side. He asks Frogger to find his daughter, Princess Dar, and considers giving her to Frogger since he is looking for a princess, but Dar warns Frogger that Princess Joy is in greater and more immediate need.
Princess Dar is the daughter of Count Blah. Frogger searches the catacombs for her at the request of Count Blah, with the promise that she may be the princess he is looking for. Unfortunately, she is not, but she does help Frogger escape the catacombs and reach Joy Castle.
Big Mama is the heavyset goblin wife of King Ijnek. She hits him with her rolling pin for being incompetent. After Frogger defeats King Ijnek, she is never seen or mentioned throughout the rest of the game.
